Bought my ATP 12/27/2011. Have not contacted Garret yet. Not sure about the warranty. While detecting in the field, the head just fell off! Looks like it had been going on for awhile and snapped where the two screws attach. I am very careful about my machine and always keep it on my truck seat and hang it up when done. Anyone else? I think I can fix it myself, but not sure how yet... Any comments and info is greatly appreciated! BTW.. wrapped it up with electric tape and was able to finish the day!
